{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get
under a vehicle when it is supported only by a
jack.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to ®t the
jack lift head into the proper location before
raising the vehicle.
3. Position the jack under the vehicle.Front Tire Flat:If the ¯at tire is on a front tire of
the vehicle, you'll need to use the jack handle (C)
and only one jack handle extension (D). Attach
the wheel wrench to the jack handle extension.
Attach the jack handle to the jack. Position the jack
on the frame behind the ¯at tire where the frame
sections overlap. Turn the wheel wrench clockwise
to raise the vehicle. Raise the vehicle far enough
off the ground so there is enough room for the spare
tire to clear the ground.Front Position

Rear Tire Flat:If the ¯at tire is on a rear tire of the
vehicle, you'll need to use the jack handle (C)
and both jack handle extensions (D). Attach the
wheel wrench to the jack handle extensions. Attach
the jack handle to the jack.On all 1500 Series
vehicles, use the jacking pad provided on the rear
axle. On 2500 series vehicles, use the axle between
the spring and shock bracket. Turn the wheel
wrench clockwise to raise the vehicle. Raise the
vehicle far enough off the ground so there is enough
room for the spare tire to clear the ground.

{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if you need to, to
get all the rust or dirt off.
5. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{CAUTION:
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.
6. After mounting the
spare, put the wheel
nuts back on with
the rounded end of the
nuts toward the
wheel. Tighten each
wheel nut by hand.
Then use the wheel
wrench until the wheel
is held against the
hub.

8. Tighten the nuts ®rmly in a crisscross sequence as
shown by turning the wheel wrench clockwise.
{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose
and even come off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque speci®cation. See ªCapacities
and Speci®cationsº in the Index for wheel nut
torque speci®cation.
Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque speci®cation. See ªCapacities and
Speci®cationsº in the index for the wheel nut torque
speci®cation.

When you reinstall the full-size wheel and tire, you must
also reinstall the wheel cover with attached plastic
nuts, the plastic nut caps or the smooth center cap.
·If you are reinstalling a wheel cover with attached
plastic nuts, place it on the wheel and tighten the
nuts by hand to get them started. Then tighten
the nut caps with the wheel wrench until they are
snug. Do not overtighten the nut caps or they
may break.
·If you are reinstalling plastic nut caps, tighten the
nuts by hand to get them started. Then tighten
the nut caps with the wheel wrench until they are
snug. Do not overtighten the nut caps or they
may break.
·If you are reinstalling the smooth center cap, place
it on the wheel and tap it into place until it seats
¯ush with the wheel.
Storing a Flat or Spare Tire, Jack and
Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision,
loose equipment could strike someone. Store
all these in the proper place.
Notice:An aluminum wheel with a ¯at tire should
always be stored under the vehicle with the
hoist. However, storing it that way for an extended
period of time could damage the wheel. To avoid
this, always stow the wheel properly with the valve
stem pointing down and have the wheel repaired
as soon as possible.
